Dairy producers the world over rely on BOC to overcome the handling and processing challenges specific to milk-based products. The right freezing and chilling technologies can be instrumental in preserving quality, extending shelf-life and preventing the premature deterioration typically caused by microbial growth and rancidity.

Putting a chill on spoilage

Our freezing and chilling solutions are designed specifically to combat microbial growth and rancidity by giving you precise control over processing and packaging temperatures at your plant. The gentle handling and rapid processing capabilities of our CRYOLINE^® freezers are particularly suited to sensitive dairy products as they remove heat quickly, enabling you to meet both food safety standards and consumer quality expectations.

In addition, our experts will work closely with you to help you identify the Modified Atmosphere Packing (MAP) solution best suited to extending the shelf-life of your specific products. We offer tailored gas mixtures for everything from hard and soft cheeses to yogurts, cottage cheese and cream. You can also rely on our innovative, eco-friendly in-transit refrigeration solutions to maintain the quality of your dairy products once they leave your factory.

CRYOLINE Cryogenic Freezers

State-of-the-art cryogenic freezers such as the CRYOLINE PE inline pellet model for freezing pellets of dairy sauces or liquids

ACCU-CHILL In-line Chilling Systems

Chilling of dairy sauces using ACCU-CHILL

MAPAX Packaging Solutions

Our MAPAX blends for dairy were created specifically to overcome the challenges associated with microbial growth, rancidity and mould

FROSTCRUISE In-transit Refrigeration

FROSTCRUISE in-transit refrigeration systems keep sensitive dairy products at the quality-critical temperature range during transport

Gases

Carbon Dioxide (CO₂)

Carbon dioxide is used in Modified Atmosphere Packing (MAP) to inhibit the growth of fungi and bacteria

Liquid carbon dioxide is used in cryogenic freezing & chilling applications

Carbon dioxide is used in the carbonation of fizzy drinks and for food inerting applications

Oxygen (O₂)

Oxygen is used in Modified Atmosphere Packing (MAP) to maintain the quality, flavour, texture and appearance of food

Nitrogen (N₂)

Nitrogen is used in Modified Atmosphere Packing (MAP) to prevent oxidation and reduce odours

Liquid nitrogen (LIN) is used in cryogenic freezing & chilling applications

Nitrogen can also be used for food inerting applications and for increasing the strength of plastic drinks bottles

Gas Mixtures

Oxygen, nitrogen and carbon dioxide can be combined in various quantities to produce the ideal preservation gas for any food type.

Supply

Cylinders

BOC Food Fresh cylinders and Manifolded Cylinder Pallets (MCP) have been developed for food businesses using modified atmosphere packaging (MAP).

Food Fresh cylinders can be supplied as single gases or as mixtures. Your BOC sales and technical specialist will advise on the appropriate mixing equipment, or pre-mix cylinders. Where a pre-mix gas is chosen, BOC will advise on the exact gas mixture for packing your product.

Cryospeed

BOC’s Cryospeed service gives you access to larger volumes of oxygen, nitrogen and carbon dioxide in cryogenic liquid form. These are stored in fully maintained stainless steel vacuum-insulated vessels on your site and are filled by our Cryospeed operators. Our storage vessels are set up for the pressures, flow rates and sizes appropriate to each customer. All rented vessels are fully maintained under the supply agreement with BOC.

Bulk

High gas volumes can be stored in BOC bulk cryogenic vessels. These are installed at the customer’s site, providing a continuous and secure supply of oxygen, nitrogen or carbon-dioxide. Our Customer Engineering Service (CES) designs, installs and maintains the vessel in line with customer requirements and in compliance with all the relevant regulations (such as the Pressure Systems Safety Regulations 2000). Our On-Stream service can also cover customer-owned systems.

On-site generation

For those needing generated nitrogen, the BOC Ecovar-mini range provides an on-site generation solution at a range of pressures, flow rate and purity. On-site generation requirements are assessed on a site-specific basis to ensure the resulting set-up will cater for your needs now and in the future.
